Olutasidenib With Azacitidine Followed by Olutasidenib Maintenance for the Treatment of IDH1-mutated Acute Myeloid Leukemia in Patients With Prior Treatment With Venetoclax Plus a Hypomethylating Agent

This phase II trial studies how well giving olutasidenib with azacitidine, followed by olutasidenib maintenance, works in treating patients with IDH1-mutated acute myeloid leukemia (AML) who have received prior treatment with venetoclax plus a hypomethylating agent (HMA-Ven). Olutasidenib and azacitidine may inhibit the growth of cancer cells by blocking certain enzymes required for cell growth. Maintenance therapy can help prevent or delay cancer from coming back. Olutasidenib with azacitidine followed by olutasidenib maintenance may be effective in treating patients with IDH1-mutated AML who have received prior HMA-Ven.

Participants receive olutasidenib orally (PO) twice daily (BID) on days 1-28 of each cycle and azacitidine intravenously (IV) or subcutaneously (SC) for seven days of each cycle as per schedule determined by the investigator. Cycles repeat every 28 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive olutasidenib PO BID on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo bone marrow aspiration and biopsy, and blood sample collection throughout the study. After completion of study treatment, patients are followed up within 30 days and then every 4 months until withdrawal of consent, lost to follow-up, study termination, or death.
